DockerSlim => SlimToolkit (slim.ai)

slimtoolkit/slim: Slim(toolkit): Don't change anything in your container image and minify it by up to 30x (and for compiled languages even more) making it secure too! (free and open source) @GitHub 

(Go, Apache 2)

Optimize Your Experience with Containers. Make Your Containers Better, Smaller, More Secure and Do Less to Get There (free and open source!)

Note that DockerSlim is now just Slim (SlimToolkit is the full name, so it's easier to find it online) to show its growing support for additional container tools and runtimes in the cloud native ecosystem.

Slim is now a CNCF Sandbox project. It was created by Kyle Quest and it's been improved by many contributors. The project is supported by Slim.AI.
